Baldor NEMA 1/IP 50...Cat# BC140

[Mwills]

I'm having troubleshooting issue with this unit..I work on them often but a little stumped..this unit is on a flex conveyor and I get power to everything. But as soon Ias i switch to forward or reverse i pop the gfci. Can anyone steer me in the direction..or ask me a question if i didnt give enough info. Amazon has 5 conveyors down and all having same issue. the odd thing is they were all running a dayvor so ago..
Thanks in advance

I know this is an old post and I hope you resolved it by now, but are all 5 motors on the same circuit? or are there five individual GFCI's?

Do conveyors need to stop completely before changing direction?
